Description Janis Steinfeld

2010-11-19 11:55:12 EST

Build Identifier: 3.6.1

The following exceptions are written to the workspace log when the help system is first invoked when running Rational Software Architect, version 8.0.1. They are coming from the GMF docs.  They do not affect the functioning of the help system but our testers would like to see this fixed.

Comment 1 Aurelien Pupier

I don't find where is the source code for org.eclipse.gmf.doc

Effectively on the extension point org.eclipse.help.toc, they are reference to toc-runtime.xml and toc-tooling.xml which are not in the plugin.

So where is this plugin?

Comment 2 Aurelien Pupier

2011-02-16 19:25:33 EST

Finally found it in 
org.eclipse.gmp/org.eclipse.gmf.tooling/doc/org.eclipse.gmf.doc

There are links in toc.xml to toc-runtime.xml and toc-tooling.xml but the file no more exist.

Should we just remove the link inside toc.xml and the reference in extension point or the toc-runtime.xml and toc-tooling are available somewhere and just ,need to put them back  in this plugin?

Comment 3 Aurelien Pupier

2011-02-16 19:26:43 EST

assigning to GMF-tooling as the plugin is in org.eclipse.gmf.tooling source code

*** Bug 391912 has been marked as a duplicate of this bug. ***

Comment 5 Praveen Bahl

2013-04-15 04:59:13 EDT

Has this been resolved in IES 4.2.2 . 
We are still getting the similar issue even after adopting IES 422

Comment 6 Tao LI

2013-04-21 21:13:32 EDT

We can also see this issue when our product (based on eclipse 422) start in a new workspace and invoke the Help->search for the first time . The trace is as below, Do we have any steps  or patch could be used to avoid this issue ?

Thanks .
